Application December 17, 1947, Serial No. '792,211

This invention relates to a dipper for ice cream or the like and hasforits primary object rapidly to enter the frozen body of ice cream tocut therefrom the material which is to be contained in the dipper.

Another object is to facilitate the ejection of the contents of thedipper after it has .been filled.

The still further object is to preserve the parts which Contact the icecream in a sanitary coni dition; and avoid the collection of germs andbacteria thereon.

The above and other objects may be attained by employing this inventionwhich embodies among its features a cup mounted to rotate about itslongitudinal axis, a stationary scraper blade within the cup, the bladeconforming to the contour of the inner side wall of the cup, and meansfor rotating the cup.

Still other features include an elongated hollow handle, a shaftadjacent one end of the handie, said shaft being fixed against rotationand lying along an axis which lies perpendicular to an intersects thelongitudinal axis of the handle, one end of the shaft projecting beyondthe peripheral coniines of the handle, a sleeve rotatably mounted on theshaft and projecting at one end beyond the peripheral confines of thehandle, a cup mounted on the sleeve to rotate therewith about itslongitudinal axis, a scraper blade fixed to the shaft within the cup andconforming in shape to the inner side wall of the cup, an electric motorwithin the handle, speed reduction gearing in the handle to establishdriving connection between the motor and the sleeve, and means on thehandle within easy reach of the user to control the energization of themotor.

Figure 2 is a fragmentary front view of the clipper,

Figure 4 is a horizontal sectional view taken substantially along theline t--t of Figure 1, and

Figure 5 is a horizontal sectional view taken substantially along theline 5-5 of Figure 1.

Referring to the drawings in detail the ice cream dipper comprises ahandle designated gen-` erally I0 and a scoop designated generally l2.The handle comprises a tubular body portion lf3 into one end of which isslidably tted a cap IG having an axial opening I8 for the reception of abushing 20 through which a pair of insulated 1 Claim. (Cl. 107--48)electrical conductors 22 enter the handle It. This cap carries anannular iange l1 which slidably enters the tubular body portion l.' andforms a stop by which the motor, to be more fully hereinafter described,is located in the handle l0.

Mounted within the tubular body I4 is an electrical drive motor 25having a drive shaft which carries a spur pinion 2S for a purpose to bemore fully hereinafter explained. One of the conductors 22 is connecteddirectly to the motor while the other conductor is connected to aconventional push butto-n mechanism 2 which in turn is connected in aconventional manner to the terminal of the motor opposite that to whichthe other conductor 22 is connected. As shown one end of the motor 24engages the flange I1 which forms a seat for the motor and by extractingthe flange il from the tubular body I4 the cap lli may be removed toallow the motor 2li to be extracted from the handle for Servicing.

Extending transversely through the tubular body M adjacent the endremote from the cap I6 are supporting bars 28 in which a suitable speedreduction gear train designated generally 3l! is supported. One gear 32of the speed reduction gear train 39 has meshing engagement with a spurpinion 38, the purpose of which will be more fully hereinafterexplained.

Slidably tted in the end of the tubular body i4 remote from the cap i6is an end wall 38 provided with an axial bore 4|] which aligns axiallywith the gear 26 of the motor 24, and mounted for rotation in theopening lil is a shaft 42 to which the gear 36 is fixed in anyconventional mannerl 'I'he end of the shaft 42 opposite to that carryingthe gear 3E has coupled thereto for rotation therewith a beveled pinion44 the purpose of which will be more fully hereinafter described. Owingto the fact that the end wall 38 is slidably coupled with the tubularbody I4 it is obvious that by merely withdrawing it axially from thebody ld, the gears 36 and 34 will be disengaged and access may be had tothe interior of the tubular body lli and the gear train 30.

Slidably iitted on the end of the wall 33 remote from the body I4 is acap i5 through which extends diametrically opposed axially alignedopenings t8 and 5t. The opening 5H is internally screw threaded toreceive a bushing 52 in which a sleeve 5ft is mounted to rotate. Thebore of the sleeve 5&3 is substantially equal in diameter to thediameter of the opening 48, and extending through the opening i8 and thesleeve 54 is a shaft 56 carrying adjacent the wall of the 3 cap 46formed with the opening t8 a set collar 58. The end of the shaft 56which projects through the opening 43 is externally screw threaded toreceive a clamp nut 60 which is adapted to cooperate with the set collar58 in locking the shaft 56 against rotation,

Fixed to the inner end of the sleeve 54 is a beveled pinion 52 which asillustrated in Figure 1 when the parts are assembled has meshingengagement the beveled pinion 44, and xed to the outer end of the sleeve54 is a cup 34 forming the ice cream scoop previously mentioned. The endof the shaft 56 remote from that carrying the nut 6B projects axiallythrough the cup 64 and has welded or otherwise fixed thereto a scraperblade 66 which as illustrated in Figures 1 and 2 conforms to the concaveinner face of the wall of the cup 64 so that as the latter is rotatedabout the axis of the shaft 5S, its entire inner surface will be scrapedby the blade.

In use the handle l!) is grasped in the hand of the user and pressureapplied to the push button 26 to energize the motor 24 and set thepinion 26 into operation. Rotation of the pinion 26 will drive the geartrain 30, thus to impart rotary motion to the shaft l2 which istransmitted through the beveled pinions 4 and 62 through the sleeve 54and thence to the cup 54. The rotation of the cup winll facilitate itsentrance into the body of ice cream or the like to be dispensed andenable the cup to easily and quickly be lled. Upon extracting the scoopl2 from the body of ice cream pressure is released on the button 26 sothat the contents of the cup 64 may be transferred to any desired pointfor discharge therefrom. Discharge of the contents of the cup may easilyand quickly be attained by pressing the button 26 to cause the cup torotate about the scraper 69 with the result that the contents of the cupwill be scraped loose therefrom and may be deposited in any suitablereceptacle.

While in the foregoing there has been vshown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

Having described the invention, what is claimed as new is:

An ice cream dipper comprising a tubular body having an open forwardend, supporting bars within the body at its open end, a speed reductiongear train supported on said bars, an electric motor within the body andoperatively connected to said gear train, a cap, an end wall joining thecap to the open end of said body and closing the open end of said body,said cap being removable from said body for access to said gear train,said end wall having a central opening, a shaft rotatably mounted insaid central opening and including forward and rear ends, a driven shaftrotatably supported by said cap and disposed at right angles to said rstnamed shaft, one end of said driven shaft projecting outwardly from thecap, a cup mounted on the outwardly projecting end of said driven shaft,a beveled gear on the forward end of said first mentioned shaft andlocated within the cap, another beveled gear on the driven shaft locatedwithin the cap and meshing with the first named beveled gear, and a gearon the rear end of saidv first mentioned shaft meshing with said geartrain.
